Description

A kind of modular multi-function Variabale valve actuation system for 4 cylinder IC engines
Technical field
The present invention relates to a kind of modular multi-function Variabale valve actuation system for 4 cylinder IC engines, belong to the drive system that can realize internal-combustion engine variable valve.
Background technique
Along with the fast development of World Economics, the problem of energy and environment has become the major issue that affects sustainable economic development.Internal-combustion engine, as the dynamic power machine being most widely used in the world at present, is consuming every year a large amount of fuel oils, and is discharging a large amount of harmful gases and particulate, and combustion engine energy-saving emission reduction work is very urgent.Changeable air valve technology, because it is in the potentiality of improving aspect engine performance, has been subject to the extensive concern of domestic and international internal-combustion engine research institution and enterprise.In addition, along with the sharply increase of internal-combustion engine recoverable amount, annual people's life and the property loss causing because of traffic accident increases year by year, and vehicle safety is more and more subject to people's attention, and increasing country classifies auxiliary braking system one of as indispensable annex of vehicle.But at present the auxiliary braking system such as electric vortex buffering module, hydrodynamic retarding module mostly exist in running brake member easily overheated, retardation efficiency reduce too fast, stopping power controllable degree is low, the easy sideslip of vehicle, braking system take the problems such as limited vehicle space during braking.Motor auxiliary braking system can be avoided these problems well.In current motor auxiliary braking system, the retardation efficiency of the decompression type auxiliary braking system of 720 ℃ of A/ circulations is the highest, and still, this system still exists the problem that braking force is less.Day by day urgent energy-saving and emission-reduction and vehicle safety demand driving valve actuation system be to independent adjustable between circulation, between cylinder, between valve Operational Limits (valve opening timing, maximum lift, unlatching duration), to the future development of whole-variable valve actuating system.For above problem, the exploitation of a set of Variabale valve actuation system that simultaneously meets the drive pattern of 720 ℃ of A/ circulations of internal-combustion engine and the gas compressor formula braking mode of 360 ℃ of A/ circulations is extremely urgent.
At present, practical Variabale valve actuation system has retained valve cam mostly, adopts mechanical structure, is mainly divided into: 1) camshaft phase modulation formula, as the Vanos system of the VVT system of TOYOTA, BMW etc.; 2) lift range variable formula stage by stage, as VTEC system of Honda etc.; 3) continuously variable valve lift formula, as CVVL system of the Valvetronic system of BMW, Hyundai etc.This type systematic, by controlling intermediate transmission mechanism, regulates keying timing and/or the range of the each cylinder valve of internal-combustion engine.
Compared with there being cam Variabale valve actuation system, without camming, can realize valve event more flexibly, complex structure simultaneously, cost costliness, and need to carry out more deep research at aspects such as reliability, serviceability and the controls of valve temperature compensation.This type systematic mainly comprises electromagnetic type and electrolyte type two classes.Electromagnetic type system remains to be further improved at aspects such as accurately control of motion, the adjustable degree of valve lift.Compared with mechanical type and electromagnetic type system, electrolyte type system has the features such as the relatively higher adjustable flexibility ratio of valve, higher specific power, flexible arrangement, is the Variabale valve actuation system of at present tool potentiality.This system mainly comprises common rail oil feeding type and the large class of cam oil feeding type two.
Altogether rail oil feeding type system has been cancelled valve cam, by controlling in the open/close states of solenoid valve and accumulator, drives oily pressure, regulates keying timing and the range of valve.Ford company, Lucas company etc. carried out research to this, still need carry out deep research at system cost, speed of response, the aspect such as take up room.Along with the increase of internal combustion (IC) engine cylinder number, single cylinder valve number and rotating speed, this system also exists: the 1) problem of bulky, the difficulty in arrangement of common rail pipe; 2) quantity of the high-speed large-flow solenoid valve using in system is too much, and the solenoid valve cost being determined by current solenoid valve material and processing technology is higher, and therefore, the holistic cost of this system is higher.These problems have caused the practical comparatively difficulty of the traditional electricity of rail oil feeding type altogether liquid Variabale valve actuation system.
By comprehensive mechanical formula and the advantage of rail oil feeding type system altogether, cam oil feeding type system has been subject to the extensive concern of researcher and production firm, as the VCM system of the Multiair system of Fiat, ABB etc.This type systematic adopts cam-plunger type oil feeder to replace accumulator, takes up room little, can realize the synchronization regulation between keying timing and the stroke three of valve.Still need to aspect following two, be improved: the first, the quantity of the required oil feeder of system and solenoid valve is more, entire system high expensive; The second, valve operation adjustable extent is subject to the restriction of fuel feeding and control gear, cannot realize valve and open and close the independent regulation between timing and stroke three, does not also realize the valve running of 360 ℃ of A/ circulations of internal-combustion engine auxiliary braking pattern requirement etc.
For these problems of cam oil feeding type system, there is a kind of cam oil feeding type electricity liquid valve actuation system, this system adopts the mode of cam-plunger fuel feeding, because it cancels common rail pipe, and has reduced the quantity of oil feeder, and system space is arranged easily.But this system still exists following two problems to have to be solved: the problem that 1) quantity of the required solenoid valve of system too much, system cost is higher; 2) valve actuation adjustable extent is subject to the restriction of cam-plunger oil feeder fuel supply rate curve, cannot realize exhaust valve secondary opening event, cannot realize the desired changeable air valve event of gas compressor formula braking mode etc. that the internal-combustion engine of 720 ℃ of A/ circulation is become to 360 ℃ of A/ circulations, these have limited the functions expanding of this system.
For the existing problem of cam oil feeding type electricity liquid valve actuation system, there is a kind of double mode whole-variable valve actuating system, this system is by use drive-braking cycle device and mode converter, reduced solenoid valve quantity, and realized and meet internal combustion engine drive and the desired changeable air valve event of braking mode simultaneously.But, it is to be solved that this system still exists following problem to have: two five-way valves that 1) use due to system need to switch the in the situation that of the different pressure reduction of each hydraulic fluid port, and the pressure reduction situation of change of each hydraulic fluid port is very complicated, and, along with the increase of rotating speed, require the response time of two five-way valves shorter, circulating rate is larger, these requirements have caused two five-way valve structure complexity, and processing cost is high; 2) under internal combustion engine drive pattern, this system cannot realize within the oil feeder fuel feeding stage and close valve, this by limit this system idling for internal combustion engine and in the performance improvement degree of low operating mode, and these operating modes conventional operating mode of city vehicle exactly, oil consumption and emission behaviour when under these operating modes, the runnability of internal-combustion engine has determined vehicle actual motion to a great extent; 3) driving-braking cycle device complex structure, external oil pipe quantity is more, has reduced the manufacturability of system, has increased the cost of system and has arranged difficulty; 4) between various parts, function interdepends, and for different application requirement, need to change multiple parts and entire system and arrange, has limited the application area of system.
For cam oil feeding type electricity liquid valve actuation system and the existing problem of double mode whole-variable valve actuating system, there is in recent years a kind of intensive multifunction changable valve actuation system, simplified the structure of solenoid valve, and realized under internal combustion engine drive pattern and close valve within the oil feeder fuel feeding stage.But this system still exists following two problems to have to be solved: 1) rotary selector complex structure, external oil pipe quantity is more, has reduced the manufacturability of system, has increased the cost of system and has arranged difficulty; 2) between various parts, function interdepends, and for different application requirement, need to change multiple parts and entire system and arrange, has limited the application area of system.
Summary of the invention
The object of the invention is to: 1) by the design phase, limit module and reach fuel oil supply unit and the solenoid valve few with quantity, and the simple as far as possible solenoid valve of structure is realized the object of internal combustion engine drive and the desired changeable air valve event of braking mode, thereby reach when realizing internal-combustion engine variable Valves Technology and auxiliary braking technology and uniting two into one, significantly simplied system structure, the object of reduction system cost; 2) the simplification stage limits the structure of the system core parts such as module as far as possible, reduces the quantity of external oil pipe, improves the manufacturability of component, reduces system cost; 3) by adopting modular design method, by the functional independence of various parts, to reach by application request, carry out selecting system parts, and without system miscellaneous part and entire system are arranged to the object changing, the adaptability of enhancing system to type, the application area of extension system; The final market acceptance level that improves native system.
